FIREPLACE.

Specification of Letters Pateht No. 31,785, dated March 26, 1861.

To all whom it may concern:

Be it known that I, B. F. COWAN, of Memphis, in the county of Shelby.and State of Tennessee, have invented a new and useful Improvement inFireplaces; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification, in which'Figure 1, is a front viewof a fire place constructed according to theplan'of my invention. Fig. 2, is a vertical transverse section of thesame.

Similar letters of reference in each of the several figures indicatecorresponding parts.

The nature of my invention consists, 1st, in the combination of a gratewith an air space at the back thereof, and a passage coinmunicating withthe outside of the apartment or house in which the grate is situated,whereby the air consumed is taken from the outside of the apartment soas to keep the air inside of the room pure, and also assist in a moreperfect radiation of the heat, in the manner hereinafter described.

It consists, 2nd, in the combination with the above mentioned grate, airspace and air passage of the peculiar form of radiator substantially ashereinafter described.

' To enable others skilled in the art, to make and use my invention Iwill proceed to describe its construction and operation.

A, represents the grate of a fire place; it may be constructed in theusual manner. Behind this grate, I construct an air space B, said airspace extending the entire width of the grate and being closed on alevel with the top of the same, as represented in the drawing. The airspace connects with a passage C, leading from the outside of the houseor apartment and used for the purpose of admitting air into the space orchamber B, from whence it is forced through the grate and the body ofthe coal contained therein, into the room, thereby insuring thedeliverance of a greater amount of heated air than by the usual methodof feeding the fire from the inside of the room.

D, is the back or radiator; it is constructed in the manner representedin the drawings. The peculiar shape which I have there represented, Ideem the best to secure a perfect radiation of the heat.

E, is a flue leading from the top of the back or radiator; it serves asan escape passage for the products of combustion.

It will be observed that the air space B, is closed on a level with thetop of the grate. This is done in order to force the air through thebody of the coal and prevent its passage up behind the same and so on upthe chimney where it would escape.

I sometimes construct my grate'in a manner to have the front thereofform a slight longitudinal concave.

What I claim as my invention and desire to secure by Letters Patent,is-- l. The arrangement of a grate A, with an air space B, in the mannerdescribed, at the back thereof, and a passage C, communicating with theoutside of the apartment or house in which the grate is situated, as andfor the purposes set forth.

2. The combination with the above mentioned grate A, air space E, andair passage C, of the form of radiator D, shown, as and for the purposesset forth.
